UTG PRO AR15 Ops Ready S4 Mil-spec Stock Kit, Black RBUS4BM

The UTG PRO AR15 Ops Ready S4 Stock Kit is a compact, lightweight stock system designed for AR-15 platforms. Its minimal bulk profile and 4.28-inch length make it ideal for short-barreled rifles (SBRs) and situations requiring maneuverability, such as tactical operations or close-quarters engagements. The stock offers four-position adjustability, allowing users to customize the length of pull for optimal comfort, even when wearing load-bearing vests or plate carriers. Constructed from impact-resistant, high-strength polymer, it ensures durability under heavy-duty use. The ergonomic slanted cheek rest and rubberized butt pad enhance shooting comfort and stability. Additionally, the stock features a reversible sling swivel housing for both left- and right-handed shooters, as well as a standard sling loop for traditional slings. The kit includes a mil-spec extension tube, buffer, buffer spring, receiver end plate, and castle nut, providing a complete solution for upgrading or building an AR-15.
